Sneak a peek through the mist to technology of the future

A tabletop display with personal screens made from a curtain of mist that allow users to move images around and push through the fog-screens and onto the display, will be unveiled at an international conference later this month.

The research paper, to be presented at one of the world’s most important conferences on human-computer interfaces - ACM CHI 2014 [26 April-1 May], could change the way people interact and collaborate in the future.

These personal screens are both see-through and reach-through. The see-through feature provides direct line of sight of the personal screen and the elements behind it on the tabletop. The reach-through feature allows the user to switch from interacting with the personal screen to reaching through it to interact with the tabletop or the space above it.

The personal screen allows a range of customisations and novel interactions such as presenting 2D personal content on the screen, 3D content above the tabletop or supplementing and renewing actual objects differently for each user.

Sriram Subramanian, Professor of Human-Computer Interaction, in the University’s Bristol Interaction and Graphics group, said: “MisTable broadens the potential of conventional tables in many novel and unique ways. The personal screen provides direct line of sight and access to the different interaction spaces. Users can be aware of each other’s actions and can easily switch between interacting with the personal screen to the tabletop surface or the interaction section. This allows users to break in or out of shared tasks and switch between “individual” and “group” work.

“Users can also move content freely between these interaction spaces. Moving content between the tabletop and the personal screen allow users to share it with others or to get exclusive ownership over it. The research team believe MisTable could support new forms of interaction and collaboration in the future.”

With the new system, having personal screens for each user allows the view of each of the users to be customised to them, as well as maintaining all well-established tabletop interface techniques like touch and tangible interactions.

About the Bristol Interaction and Graphics

The Bristol Interaction and Graphics (BIG), based in the University of Bristol’s Department of Computer Science, is united by a common interest in creative interdisciplinarity. BIG acts as a hub for collaboration between social scientists, artists, scientists and engineers to combine efficient and aesthetic design. The group is particularly interested in areas which couple the design of devices with deployment and evaluation in public settings. Members of the group have expertise in research areas spanning human-computer interaction, visual and tactile perception, imaging, visualisation and computer-supported collaboration.
